Well for starters please use the video thread.
Now to your Yoshi. I saw two eggs...that's pretty pathetic.
For your opponent, he was the biggest scrub. He could've punished you horribly, airdodged, DId and wouldn't have died at like 119%. Your attacks were beyond obvious and he just doesn't believe in dodging apparently. Still, you have a lot to improve on. This is okay for starting out, but making a combo video of one persons friendlies is a bit....odd.
Not to be mean, but I'm just saying we get a lot of people wanting critiquing. and you may not have asked for it, but I think you need it. Everyone needs criticism. i didn't go in depth or harsh at all.
But I will say to get better, you have to play people who are better than you. Playing a LV9 CPU, would probably beat playing him.
Sorry for my harshness. I don't want to be mean, but I want to help you get to being a good Yoshi player.
